The Waterlase MD is a revolutionary device that combines YSGG laser energy and water to perform many traditional dental procedures with fewer anesthetics.

The following case involved a gingivectomy (gum trimming/contouring) followed by the removal of caries:

The patient presented subgingival dental caries on #13 (buccal), but was apprehensive of drilling and injection. I was able to convince the patient that there will be minimal discomfort by using Waterlase, as compared to the traditional method of drill, injection and scalpel.

Furthermore, excessive bleeding of the gums was also a concern for me. Bleeding of the gums would make it difficult to do any restorative work on the spot, but Waterlase would ensure minimal bleeding.

I used a recommended setting as provided by Biolase Technologies. This is the minimum setting you can use to achieve maximum results for a gingivectomy. There was no bleeding throughout the entire treatment.

The next step involved the removal of dental caries. Again, I used the Waterlase but required a higher voltage for gross caries free. The use of this setting was a tip I picked up during the World Laser Conference I attended in March 2007.

For the final step, I reduced the voltage (while keeping the same water and air settings) to help smooth the edges and etch the preparation. As compared to traditional methods, laser etching with Waterlase, helps to create a stronger bond between the tooth and material. The tooth is now ready for restoration.

A composite resin was used for the final restoration.

The entire procedure was done in a single session, without the use of any local anesthetic. It was a relief for the patient as he did not experience any pain or discomfort during the treatment. If a patient were to experience any discomfort (although unlikely), I recommend applying topical cream to help relieve the pain.

Laser technology is redefining today’s dentistry and has helped me to give my patients less invasive and more precise treatments. Patient anxiety is also greatly reduced with fewer shots and anesthetic. As a dentist, using the Waterlase has allowed me to widen the scope of my capabilities.
